Pick one target style per plane and aim for that and it'll do that one style muuuch better than aiming for multiple styles.
I think he has a point....but if you want to try a light freestyle plane....go for it.

Now pilots use 10.11.12 inch propellers.
You have to look at the brake down the fly.
I fly with 10 propeller speed down very slowly

When you set the speed for downline braking, do you set the prop rotation speed just slow enough before it pulls the plane on the ground? Or do you make it spin as slowly as possible but still spin?

Also, do you have your throttle on switch so you can flip it when ready to fly, and off to arm the ESC?
